You are probably still 1 (or more) views off. The parent view controller needs to do layout to adjust to your changes, and there is no guarantee that self.view.superview is the view that needs layout to do it. You probably want self.parentViewController.view for that.
It likely works if you call it twice because of implementation details of layout. -- David Duncan @ My iPhone > On Jun 17, 2016, at 2:27 AM, Torsten Curdt <[email protected]> wrote: > > This is odd.
